Darwin went to the continents of Africa and South America, wherein both of them have a tropical grassland/Savanna biome. The grasslands in these continents gave him a chance to notice that species do vary globally. He observed the similarities between the different large, flightless birds species–rheas, ostriches, and emu.
None of the above is the answerr
Answer:
D. G2 phase and M phase
Explanation:
<em>If we are looking for what takes up 25% of the graph, that would be the last option. If you look at G1, it takes up about 50%. So</em>, G1 phase and M phase <em>would take up more than that, and we want 25% not 50+. The </em><em>M phase and S phase</em><em> would take up about a third, so no. The </em><em>G2 phase and M phase </em><em>takes up roughly 25% or, it's the closest to this.</em>
<span>The Benedictâs test is used for studying the reducing sugars.
When the aldehyde is oxidized, the copper gets reduced and precipitates, changing the blue color of the solution to orange or red color.
The darker the color indicates that the solution has higher levels of sugar or a high amount of chemicals that have been reduced in the Benedictâs test.</span>
- keystone species is the correct answer.
<u>keystone species</u> which keeps the number of other animal population in
control and low in the entire ecosystem. They play an important role
through this process and helps the food chain effectively.
dominant species - most common species; found often in the ecosystem.
invasive species - which fights for itself survival and can cause harm to
ecosystem. non-native to an ecosystem
